Here I’ll show you how you can make bias strips yourself
you need a ruler that also has angle markings on it, such as a
patchwork ruler. Place it on your fabric so that the 45° line
is positioned as in Image 1. It’s also important that you have a straight fabric edge
at a right angle, otherwise the whole thing won’t work.
as shown here in Image 2;
I usually cut my bias strips 5 cm wide; it’s easy with the
markings on the ruler, and you have enough fabric to fold over,
plus seam allowance. This is what the cut bias strips look like
if you’ve done it correctly, as shown here in Image 3
then place the strips right sides together, as shown in Image 4
and mark about 1 cm further in where you need to sew. I usually use
the width of the presser foot. Sew the two strips together there, as shown in Image 5;
then cut off the points as shown in Image 6, turn the strip over and
press it, and then you can use it for whatever you like
in the next thread I’ll show you how to sew on a bias strip,
Best regards, Inge
